I agree that this is awful.  It's another compromise API.

What's the alternative?  Keeping the documented behavior means
stretching the wording of the specification.  It more useful and I
don't expect it to cause problems in real applications.  If the
application is testing the return value it#s good, it can react.  If
it's not testing the return value it might use a truncated and
potentially unterminated string.
